Project management is one of the most important issues to fulfil organizational objectives. The project management criteria are playing a vital role for completion of any project. The aim of this paper is to evaluate five main project criteria (time, cost, quality, risk, and safety) mathematically by using a multi-criteria method in order to assist stakeholders or project managers in decision-making. The fuzzy Analytic Hierarchy Process (AHP) is selected with the use of triangular fuzzy numbers for pairwise comparison scales in prioritizing the criteria in managing projects. Utilizing the fuzzy AHP technique can facilitate uncertainty in doing evaluation. In this study, one expert who is a project manager with many years of experience was asked to carry out the evaluation. The results show that the expert’s main concern in managing project is time, and cost is the second important. The study demonstrates how uncertainty in making evaluation of multiple criteria can be solved by using fuzzy method such as fuzzy AHP, in contrary to the crisp or the traditional AHP which is based on specific values, the evaluator(s) are always ambiguous and vague to give exact judgment. Hence, the application of this fuzzy method can make the assessment outcomes more accurate, scientific, and objective. It is anticipated that this work may serve as a support tool for stakeholders in improving the project management quality level.

The first series preparation of polyaniline (PANI) - silver composites by the oxidation of aniline with silver nitrate in the 0.2 and 1 mol L-1 M aqueous solutions of acetic acid, the reaction condition produce a composite that have a conductivity of about 4000 S cm-1 at 72 wt. % (20 vol%) of silver (Ag). Scanning Electron Microscope (SEM) illustrates the formation of nanostructured Ag (nanowires) coated with polyaniline. In the second series, the preparation of polyaniline - multiwall Carbon nanotubes(MWCNTs) composites were included MWCNTs of 0.25wt %, 0.5wt % or 1wt % added to 0.1 M distilled aniline under reflex procedure with 0.3M H2S04 (pH 4) investigated by cyclic voltammetry. A cyclic potential ranged from -100 mV to 1500 mV (scan rate of 30mV S-1) at room temperature for fabricating PANI/MWCNTs composite. Images of SEM showed that the PANI/MWCNTs Nanofieber structure with diameters has the range of 50nm-70 nm. Results of current-voltage (I-V) curves showed increase in electrical conductivity with increasing proportion of MWCNTs. PANI-silver composite which has been prepared in 1 mol L-1 of acetic acid and PANI-1wt% MWCNTs composite as hydrogen sensor, the results have showed that PANI-MWCNTs sensor have more sensitivity compared to PANI-silver sensor.)

This study was conducted to evaluate the concentration of alpha particles in eighteen different brands of chips collected from Iraqi markets. The nuclear track detectors CR-39 and 500 µm were used to determine the concentrations of alpha particles emitted from samples. The effective radium content varied from (0.042-0.218) Bq/kg, and at an average (0.112) Bq/ kg. Estimations of mass exhalation rates of radon differ of (7.611-39.581) mBq/kg.d, with a mean value 20.423 mBq/kg.d, whilst the surface exhalation rates of the radon differ from (95.72-497.747) mBq/m2.d, with a mean value of 257.000 mBq/m2.d. The concentration of uranium in these samples has been found, it is change from (0.036 – 0.187) ppm, with an average (0.096) ppm. An excellent relationship was observed between the effective radium content and the uranium concentration in the chips samples. Estimation of radium content and concentration of uranium in the chips samples is important from the perspective of ensuring health, so periodic studies of radiological activity should be done using a variety of methods and techniques for the purpose of limiting the effects of radiation. The concentration of alpha particles in this study does not pose a danger to people’s health and is within the limits allowed internationally.
